House Bill 1421 establishes comprehensive litter abatement and control measures in Tipton County, Tennessee. The bill defines key terms such as "garbage," "litter," and "refuse," and outlines various responsibilities for individuals, businesses, and property owners to maintain a litter-free environment. It prohibits the accumulation of refuse that could attract rodents or create health hazards, mandates the use of closed containers for household refuse, and requires commercial establishments to use designated dumpsters. Additionally, the bill places the responsibility for litter management on construction sites, loading docks, and surrounding areas of private dwellings, while also addressing the maintenance of vacant lots and parking areas.

The legislation further stipulates that all refuse must be disposed of properly, with specific prohibitions against dumping in public waterways and the unauthorized placement of advertisements on public property. It establishes penalties for violations, including fines for ongoing infractions, and mandates that the county landfill be the sole repository for refuse, barring certain exceptions. The bill requires a two-thirds vote from the Tipton County legislative body for it to take effect, emphasizing the importance of community involvement in litter control efforts.
